Hey Folks,
I'm looking to build a charger to charge a 14.4v 3800mAh pack. Well, I really want to charge 4 of these up. But, from what I can tell, charging NiMH packs in parallel is bad.. So, I though I could build 4 charging circuits and wire them in parallel using Diodes. I've read the Data sheet on the MAX712, and It looks like what I need. I want to be able to charge these packs at around 1.25 to 1.5Amps. Source voltage will be a 18v power supply with up to 8amps output. The circuit needs to be able to handle the load while charging.. The load can peak at around 1.7Amps. I thought about using larger batteries such as D's or F's.. However, charging multiple packs at the same time would yield a faster charge.. and the most mAh I can get with other cell's is either 10000mAh with D's or 14000mAh with the F's. 4 3800mAh packs gets me longer runtime. Any help would be appreciated!
Thanks, Connor
